I promise my last pics - FA50 + raynox

I just went outside to do a quick test of the FA 50 + raynox 250

I still think this is the better of the options for cheap, easy and small macro options, because it will work with so
many lenses and can quickly be pulled off if you see something non macro you want to shoot.
As Dan pointed out the raynox does not really fit the 49mm lens but I was able to screw the clip adaptor on like a regular filter.


This grass spider is about half the size of a dime


and the crop

Took this shot of my favorite 'test' nail.... and when I downloaded it, there was a little ant off to the left.

Promise my last pic post...

Very impressive crops. Did you use a tripod? Did you use off-camera flash for the spider photos?

Hey Dan

Actually, they really were quickies this afternoon. So they just had the onboard flash. (the good thing about the raynox on the FA 50 is NO Shadow from the lens)

The nail / ant shot is flashless.

They were handheld, but I had my elbows on the ground on the spider shots, so it was well braced. The flower / fly shots were the only ones where I was not braced against something.

I thought the crops came out pretty good. I have not none much close up work since I got the K20, and I am impressed by the detail in the tighter crops. Love the sensor. Cant wait for spring and a chance to use the Vivitar 105.

Thanks for the comments. It was a fun exercise

sorry, where did you find this info?

very interesting
Wherever you want - that is basic optics. You could perhaps look into the Focal Encyclopedia of Photography (Focal Press). But you will find these basics in every good textbook and with some research I bet on the web too.

An +x diopter closeup lens has a maximum working distance of about 1/x meters; so the MSN-202 (a 25 diopter lens according to the e-bay listing) has a maximum working distance of 1/25 = 0.04m = 40mm.

Looks cool but hard to use due to the small working distance and very high magnification. I think the raynox 150 (+4.8 diopter) or 250 (+8 diopter) would be more practical.

I agree with troyz

That is more microscope than macro lens. The Dof will be paper thin so focus would be tough and the magnification would be too much for most subjects. If you are looking to shoot the eye of dead bug... it might be a cool lens, but for most things it would be un-usable IMO.

As troyz said the 150 or 250 would be much better. I have the 25 and even it is a bit too much magnigication is some situations... The 150 is probably the easiest to use but it would have less mag.
